Background: This study has conducted an experiment on 14 disabled hemiplegia (female) introduced from D rehabilitation welfare center, sorted out subjects who will enthusiastically and sincerely follow the experiment for 8 weeks (before-after), and grouped them into control group (7 people), and aquatic exercise program group (7 people). After researching the effect of application of exercise program to hemiplegia on physical function and length of lower limb, we have come to the following conclusion. In case of hemiplegia, we have concluded that aquatic exercise program can aid muscle strengthening and lower limb since aquatic exercise program activates physical function and deep muscle, showing a positive influence on muscular strength and flexibility, and a significant influence on balance of lower limb. This result is considered to make people recognize the importance of rehabilitation exercise when making a program for daily life activity, injury prevention, and treatment for hemiplegia, and we believe that such reference will be proposed as a theoretical basis for application of aquatic exercise program to hemiplegia, and further be a great aid to similar studies.

Purpose: This study was to examine the effects of an exercise program for middle-aged obese women. Method: The exercise program combined folk dance and resistance training. The subjects group consisted of 85 middle-aged obese women between 40 and 60 years of age. Three 8 week sessions consisted of a $55-80\%$ maximum heart rate (MHR) exercise for 60-90 minutes a day and 3 times a week from March to November, 2004. Data was collected through a pre- and post-exercise test before and after each session. Data was collected with Inbody, dynamometer and blood. This data was analyzed by descriptive statistics, and a paired t-test with an SPSS/PC(10.0 version) program. Results: There were significant positive changes in body weight, body fat mass, body mass index, percent body fat, muscle strength, muscle endurance, flexibility, and balance quality, but no significant positive changes in skeletal mass, fat free mass, percent abdominal fat(waist-hip ratio), visceral fat area, agility, total cholesterol, high density lipoprotein cholesterol, or triglycerides. Conclusion: This study showed that an exercise program has partially positive effects for middle-aged obese women. The results of this study show that exercise at community health centers should continue for middle-aged obese women's health.

Purpose: The purpose of this study was to examine the effects of a Tai Chi exercise program on physical function and physiological variables in patients with degenerative arthritis. Methods: The study utilized a nonequivalent control group with pretest-posttest design. Data collection was done with the elders from two welfare institutions in C-city between July I and September 22, 2007. The participants were assigned either to an experimental group (n=24) or to a control group (n=22). The experimental group participated in Tai Chi exercise for 60 minutes per session, twice a week for 12 weeks and the control group received the education about arthritis for 3 weeks. Results: Except for $VO_2max$, weight, and body fat rate, the elders in the experimental group showed significant improvement in physical function (grip strength, flexibility, balance), and physiological variables (BP) compared to the control group. Conclusion: The results suggest that Tai Chi exercise would partially improve physical function, and physiological variables. Further studies are needed to determine the effects on physical fitness and physiological variables after Tai Chi exercise in this population.

Falls associated with tripping over an obstacle can be dangerous, yet little is known about the strategies used for stepping over obstacles in older Parkinson disease. The purpose of this study was to investigate the lower extremity muscle activity on the obstacle gait according to obstacle height in older Parkinson diseases. The obstacle gait of 7 older Parkinson disease was examined during a 5.0 m approach to, and while stepping over, obstacles of 0, 25, 52, and 152mm. Seven pairs of surface electrodes(Noraxon MyoResearch, USA) were attached to the right-hand side of the body to monitor the adductor longus(AL), gluteus medius(GME), gluteus maximus(GMA), biceps femoris(BF), rectus femoris(RF), gastrocnemius(GA), tibialis anterior(TA). Electromyography data were filtered using a 10Hz to 350 Hz Butterworth band-pass digital filter and normalized to the maximum value in the analyzed phases. A one-way ANOVA for repeated measures was employed for selected electromyography variables to analyze the differences of the height of four obstacles. The results showed significant differences between 0.0mm and 25, 52, and 152mm obstacle height in TA and GA activities during the second phase(swing phase). But the more increase obstacle height, the more not increase the muscle activities. This means that the Parkinson disease stepping over obstacle inefficiency. To prevent and reduce the frequency of falls, elderly Parkinson disease maintained and improved their balance, muscular strength, neuromuscular control and mobility.

This study was a quasi-experimental study of non-equivalent control group pretest and posttest design. The purpose of this study was to determine the effect of Tai Chi exercise program on physical functions, psychological functions, and fall among the fall-prone elderly. The data were collected from September 19, 2001 to January 31, 2002. The study, conducted at two facilities located in Kwang-ju, was targeted to the ambulatory aged 60 years or older who had at least one of the key fall risk factors. Experimental group participated in Tai Chi exercise for 40 minutes per one time and three times a week for 12weeks at an auditorium. Fifty nine fall-prone elderly were assigned to 12-week Tai Chi exercise program (n=29) and control group (n=30). They underwent tests of lower muscle strength, time for chair stand, balance, flexibility, depression, falls efficacy, fear of falling, and numbers of fall at the baseline and at the 12th week. Numbers of fall and fall injuries were monitored for 16 weeks(12-weeks intervention plus 4-week follow-up periods) using fall calendar. Each participant was given a calendar to record the numbers of fall per day for a month. The calendars were collected at the last week of each month. 1. Tai Chi exercisers showed significant improvement in the strength of knee flexors, and ankle dorsiflexors and plantarflexors compared to the control group. The experimental group had improvement in the strength of knee extensors while the control group did not, with no statistical significance. 2. Tai Chi exercisers reported positive change in the average time of chair stand as compared to the control group. 3. Tai Chi exercisers had significant improvement in flexibility as compared to the control group. 4. There was no significant difference in the depression between the two groups, even though the Tai Chi exercisers maintained depression score in the same level while the others were increased. 5. Tai Chi exercisers showed significant improvements in the falls efficacy as compared to the control group. The falls efficacy was significantly improved among the experimental group while the opposite was identified among the control group. 6. The experimental group reported the significant reduction of the fear of fall, whereas control group reported the opposite. 7. Of the 59 subjects for 16weeks(12weeks intervention period and 4weeks follow up), 9 (31.0%) of the 29 in exercise group and 15 (50%) of the 30 in the control group fell (relative risk=0.62. 95% CI 0.32-1.19), even with no statistical difference. The results suggest that the Tai Chi exercise program can improve the strength of knee flexors, ankle dorsiflexors and plantarflexors, chair stand. flexibility, falls efficacy, and fear of falling for the fall-prone elderly.
